The Carbon Group located at the USGS Water Science Center in Sacramento, CA needs to purchase one (1) open path CH4 gas analyzer and associated equipment. The analyzer must operate on low power and will be used with existing fast response sonic anemometer to collect continuous measurements of methane gas fluxes at remote collection sites.
